Description:

Fmoc-NH-PEG-COOH is an amine protected heterobifunctional PEG derivatives that can be used to modify proteins, peptides and other materials via its available carboxylic groups. Fmoc group can be deprotected under basic conditions to release primary amine. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.

Physical Properties:

• Form: Off-white/white solid or viscous liquid depends on molecule weight;
• Solubility: Soluble in regular aqeous solution as well as most organic solvents;
• Reactive group: Carboxylic group (-COOH);
• Purity: >90%;

Storage Conditions:

• Store at -20 ⁰C. Avoid frequent thaw and freeze.
